THOMAS FRANCIS HAI-IESY, OF CHELSEA, MASSACHUSETTS.

AUTOMATIC DISINFECTING DEVICE.

To all whom ii may concern:

Be it known that I, THOMAS F. HAHESY, a citizen of the United States, and a resident of Chelsea, in the county of Suffolk and State of Massachusetts, have invented a new and Improved Automatic Disinfecting Device, of which the following is a full, clear, and exact description.

My invention relates to an automatic liquid disinfecting device, which is adapted to be attached to theflushing tank of a water closet, whereby a certain amount of disinfectant may be supplied to the water in the tank each time the tank is operated.

The object of my invention is to provide a device of the character set forth, whereby the water which is used to flush the bowl of the closet may be supplied with a suitable disinfectant, in order to keep the bowl clean and odorless.

The device is adapted for use in connection with any receptacle which is liable to emit odors and in which water is intermittently used to clean, such as sinks, and urinals.

A further object of the invention is to provide an adjustable device of the character set forth, which shall consist of few parts, and which is easily installed; one that is serviceable and reliable and not easily put out of order.-

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in both the figures, and in which Figure 1 is a vertical sectional view of a flushing tank with my device applied there-- to; an auxiliary supply tank is also shown; and Fig. 2 is a plan view of the tank and my device attached thereto.

The flushing tank of the closet is designated as 1, and is usually attached to a wall 4 by any suitable means. The tank is adapted to contain a given amount of water 2, which is discharged therefrom to the bowl of the closet each time the chain or other operating means is used. The operating lever of the tank is denoted by 5, and it is suitably pivotally supported in a bearing 6, carried by the side wall of the tank. One end of this lever is attached toa chain (not shown), by which it is operated Suitably supported within the tank 1 by any suitable means, such as rivets 8, is a second smaller open tank 7, adapted to contain Specification of Letters Patent.

Serial No. 585,593.

smaller tank is provided with an extending cylindrical portion 9, and in line therewith and directly above is another cylindrical member 10 of slightly less diameter and open at both its ends. This member is carried by the side wall 11 of the tank through the medium of a support 12. The cylindrical member 10 is provided with an opening in its bottom portion, into which a spray tube 13 of the outline shown extends.

A piston 14: is movable in a vertical direction in the cylindrical members 9 and 10, which serve as guides therefor, said piston being of substantially the same diameter as these guides. The upper end of this piston is provided with a central threaded opening 15, into which engages one end of a bolt 16, the bolt being held in any desired position therein by means of a lock nut 17, carried thereby. The upper end of the bolt 16 engages in a suitable opening 18 in one end of a bar 19, the bar being adjustable on the bolt and being held in such adjusted position by the lock nuts 20 and 21 carried thereby. The bar 19, adjacent its opposite end, is provided with a longitudinallyextending slot 21, into which extends one of the arms 22 of a hook-shaped member 23. The arm 22 is threaded and is adjustable vertically and longitudinally with respect to the bar 19, and may be held in any adjusted position by means of the nuts 24 and 25 with which it is provided. It is to be noted that the bar 19 extends at right angles to the lever 5, and that this lever is in engagement with the hook-shaped member 23 carried by the bar. The lever extends between the arms 22 and 26 of the hook-shaped member, being held in positionthereby.

Suppose that the large tank 1 has been filled with water to the height indicated, and that the smaller tank has been supplied with the disinfectant 27, as shown in Fig. 1. Since the outlet of the spray tube 13 is above the level of the disinfectant liquid, it is obvious that the liquid can flow from the open tank 7 into the tank 1, even if the piston 14: was removed. The parts are as shown in Fig. 1, and it is desired to operate the device. Pulling down on one end of the lever 5 will raise the opposite end and with it the bar, because of the hook 23 carried thereby, which is in engagement with the lever. As the bar 19 is raised, the piston 1% will be drawn up and out of the cylindrical extension or pocket 9 and will be guided in its movement by the member 10. The distance the piston will travel relatively to the bottom of the cylindrical pocket 9, may be varied by means of the lock nuts 20 and 21. As the piston is moved out of the pocket 9, a quantity of the disinfectant liquid will flow in, the level of the liquid in the open tank 7 and the spray tube 13 being equalized. Vhen the lever 5 has been released and the water is flowing out of the flushing tank 1, the piston 14, by reason of its weight, will come back into itsnormal position in the pocket 9, thereby forcing out a given amount of the disinfectant through the spray tube 13 and into the water in the tank 1. Thus, it will be seen that the water supplied to the bowl is provided with disinfectant at all times, the amount provided depending on the position of the piston 1st with respect to the bottom of the cylindrical pocket 9. The position of the piston may be varied by means of the lock nuts 20 and 21 carried thereby.

If it is desired to use my device in connection with a sink, the smaller open tank 7 with the piston and spray tube may be suitably supported over the sink. Of course, the large tank 1 may be dispensed with and the operating lever may be retained.

I have shown an auxiliary tank 28, supported by any suitable means, such as brackets 31, and provided with a removable cap 29, whereby a quantity of disinfectant liquid 30 may be poured in, to serve as a reservoir or source of supply, in connection with the smaller open tank 7, or, when it is desired to use a plurality of these tanks, to provide a single supply for them all. The flow of liquid from the auxiliary tank is controlled by the stem 32, carried by the float 31 in the open tank 7, which forms a needle valve. The end of the stem 32 is adjacent the opening 38 in the extension 3%, and in the position of the parts shown in Fig. 1 the valve is closed. As the liquid in the open tank 7 is used, the float 31 will drop, thereby opening the pipe 36 to the liquid in the tank 28, and the flow will continue until the rising of the float-controlled stem 32 again closes the opening 38.

Thus, it will be seen that I have provided means whereby the level of the disinfectant liquid in the smaller open tank 7, may be maintained practically constant. WVhere a plurality of flushing tanks are used, as in public buildings, hotels, etc., a single central supply tank 28 provided with a number of outlets to the various smaller tanks, may be employed.

My device is capable of application to many different uses than those enumerated.

The form, size and proportion of the parts may be varied, in order to meet different conditions, without departing from the spirit of the invention.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. The combination of a flushing tank, a tank adapted to contain a disinfectant and provided with a pocket and a cylindrical member, an outlet pipe extending from said pocket, a lever on the flushing tank, and a bar extending over the second named tank having a hook thereon in engagement with the said lever on the flushing tank, a piston entering the said pocket and the said cylindrical member, whereby as the lever is operated, an amount of disinfectant will be supplied to the flushing tank.

2. In combination, a flushing tank provided with an operating lever, an auxiliary tank adapted to contain a disinfectant and provided with an extending pocket from which a tube leads, a cylindrical member carried by the auxiliary tank, a piston carried in the said cylindrical member, a bar provided with hook-shaped member at one end thereof, the hook-shaped member being in engagement with the lever of the flushing tank, the opposite end of the said bar being in engagement with the said piston, whereby as the flushing tank is operated, the piston will enter the pocket on the second tank and cause disinfectant to be discharged into the flushing tank,

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
